Here's the process to have the birds in your yard sing beautiful musical pieces.
1- The mic in the device records the various birds singing.
2- The program determines what species of bird it is.
3- The program lines up short melodies that this kind of bird can learn and sing.
4- The program
creates melodies that the various species can sing, all in the same key, and begins the training session.
5- A training session for a particular bird starts when their tweets are analyzed and they are matched with their training session.
6- Once you have the evaluation of the various song birds in your yard, you can pick a musical piece that you like and the training sessions will start.
Keep in mind, these will be simple, based on all the melodies being in the same key so it won't be a Bach fugue you're hearing, but it will be all the birds in your yard singing in the same key, it will be a bird choir.
ADDENDUM 1: Plus it has a squirrel cannon.
ADDENDUM 2: The device looks like a little bird in a tuxedo with a baton in his hand. And it's equipped with lidar so it can turn it's head in the direction of an off key bird and wave the baton espressivo in the offender's direction.
ADDENDUM 3: The device would somehow be networked to your living room through motion controllers or something so -you- could wear the penguin suit and wave the baton in time to the music.
